Microsoft Exchange Server 2003 organizations may experience high network use because of link state updates. Exchange 2003 cannot control link state updates that are caused by user version changes. This article describes a hotfix that you can use to suppress user version changes.
Currently, you can configure the registry to control link state updates that are caused by minor version changes. Minor version changes may include changes that occur on a connector or on a bridgehead server.

Warning If you use the ADSI Edit snap-in, the LDP utility, or any other LDAP version 3 client, and you incorrectly modify the attributes of Active Directory objects, you can cause serious problems. These problems may require you to reinstall Microsoft Windows 2000 Server, Microsoft Windows Server 2003, Microsoft Exchange 2000 Server, Microsoft Exchange Server 2003, or both Windows and Exchange. Microsoft cannot guarantee that problems that occur if you incorrectly modify Active Directory object attributes can be solved. Modify these attributes at your own risk.
After you install this hotfix, you can use the ADSI Edit tool to suppress user version changes. To suppress user version changes, set the Heuristics property as follows on the organization object:
NoteThe 0x800 value is equal to the decimal value 2048.
Note In the following procedure, you must use the ADSI Edit tool that is included in Microsoft Windows 2000 Server Support Tools.
To edit the CN=OrganizationName attribute, use the following steps:
User version changes occur when there is a base-level directory service update. A base-level directory service update may occur when an Exchange Server administrator changes something at the routing group level. For example, a user version change occurs when an administrator changes a routing group name, adds a server, or removes a server. However, the primary cause of user version changes is the Windows Management Instrumentation (WMI) data that is in each server. This data states which services are running. If you stop and start a service, user version changes in the link state table (LST) will be replicated to all Exchange Server computers in the organization.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
This problem was first corrected in Exchange Server 2003 Service Pack 2.
